Overview: This document provides technical specifications for Collano Adhesives AG's range of adhesive films designed for textile applications, including interlining, floc, and labels. The document outlines the properties and performance metrics of various adhesive products.
Product Specifications:- Chemical Basis: The adhesives are based on different chemical compositions such as LDPE, HDPE, CoPa, TPU, and CoPET.
- Melting Range: The melting range varies across products, from 75–135°C.
- Melt Flow Index: This index, measured at 190°C/21.2 N, ranges from 2–60 g/10 min depending on the product.
- Density: The density of the adhesives ranges from 0.92 to 1.24 g/ml.
- ECO-Passport: Most products have an ECO-Passport, indicating environmental compliance.
- Open Time: The open time for application ranges from less than 1 second to 25 seconds.
- Heat Deflection Temperature: This ranges from 75°C to 120°C.
- Plasticizer Resistance: Only some products offer resistance to plasticizers.
Performance Metrics:- Shear Modulus: At 20°C, the shear modulus ranges from 11 to 1390 MPa.
- Modulus of Elasticity: This ranges from 12 to 438 MPa.
- Yield Stress: Yield stress values range from 2.4 to 33 MPa.
- Tensile Strength: Tensile strength varies from 16 to 57 MPa.
- Ultimate Strain: The ultimate strain is greater than 300% for most products.
Application Guidelines:- Pressing Time and Pressure: A consistent pressing time of 1 minute and pressure of 3 bar is recommended for all products.
- Minimum Bond Line Temperature (MBT): The MBT ranges from 90°C to 140°C, with pressing temperatures set at MBT + 10°C.
- Adhesive Film Weight: The weight of the adhesive film ranges from 40 to 70 g/m².
Performance Testing:- Peel Strength: Peel strength is tested at various temperatures (MBT + 10°C, + 20°C, + 30°C) with results ranging from 0.5 to 3.5 N/mm.
